Complaining about Windows Vista is a national past time on Internet forums these days. Windows Vista 'costs too much', 'has onerous product activation', 'requires too much hardware', etc. These complaints are often followed up by a very simple boast: 'I'm just going to switch to Linux'. But in today's landscape, how viable is that statment? Is the threat to switch to Linux an empty one, or is it entirely possible?"

1. a limited account user can shutdown the system and render other (more important) logged users with administrative accouts got terminated and thus corrupt their files and programs.

2. Turn windows defender off by an administrator and switch to another limited account user and you will find that "security center" gives false indicators that your security is on! now click on it and you will see that a message will popup to tell you that windows defender is off! (so an indicator that doesn't reflect the real state of your system on an enterprise machine! how comfortable!)
